fApplication led November 7, `1925, Serial No.` 67,594, andlnGreat Britain `November 27, 1924.

This linvention relates to machines for use inthe manufacture of boots and shoes for pullinguppers overlasts, and has for Vone of its important objects `the `provision of means for accomplishing better results-than heretofore in the pullingzof the upperat the side of the` last. The invention Vherein illustrated in its application-tol a-'ivell-known type ofpulling-overgmachine, the general organizationrof which is shown anddescribed in detail in various prior`United States Letters Patent( granted upon vapplications of R. `F. McFeely, particularly Patent No. 663,777, granted on December 1l, 1900 and Patent No. 1,029,387, granted on June l1, 1912. It Will be recognized, however, that the invention .is not limited to machines of the type shown in said patents.

In pulling-over `machines as heretofore constructed it hasbeen'the general practice` Where more than one gripper is provided for pulling the upper .at each -side ofithe last, to utilize at each side a pair of griliipers so arranged as `to act substantially as a unit 'Yin the upper-pulling operation, so `that/the portions of the upper which are acted upon by the different' grippersare subjected to substantially the same. treatment inrespect to the forceand'the direction of the pull. The present `invention provides an organizationhaving, for the purpose of pulling `the upper at. the side of theylast. a plurality of grippers which are operated with relative movements such to subject the different i portions ofthe upper which .are tensioned b v the respective grippers to different treatment` having regard particularly to the -differences in contourot the" last which `are encountered at different portions .of `its length.` `In accordance with one featureot the invention there isV provided. in combina.- tion with front and rear grippers for pulling the upper atthe side of the last. means for effecting relative movement of said gripper-s lengthwise of the last inthe upperpullingoperation. The best results may involve such movement of either the front or the rear grippertoward orfrom `the other gripper at the-same side offthellast. or movements of` both these grippers in `diiferent relations to eachother, in..acc`orclance With the differing characteristics of different `styles of shoes or of right and left shoes,

and the construction shown is, in fact,` so designed as to `permit various relative movements of the grippers tobe effected selectively. `It is contemplated that the rear-side gripper-Which pulls the upper at the outer side of a shoe, either. rig-ht or left, will usually best be opera-tedv'vith a rearward or reardravving movement during the updraw, to pull the upper smoothly and tightly over the `instep Vportion ot ythe last, While the rear gripper that operates atthe innerside of the shoe receives a foredrawing movement. By the construction shown the extent of such movement at either side maybe varied, `or either `rear gripper-may be operated, lif desired, Without `any componentuof movement lengthwise of the shoe. Preferably thefront side grippers Willhave a foredrawing movement, the `mechanism provided for this purpose being so designed thatltheextent of the foredratving movement may be varied or such movement may be eliminated.`

'The i invention further provides -for ivari ably positioning a gripper r or grippers lengthwise of the shoe, and ashereinillustrated automatic -mechanism` is provided i for positioning the rear side gripper' which operates at the outer sideof a shoe farther rearwardly than the corresponding gripper at the opposite side Conveniently alsoft-he machine includes means for determiningthe direction of the` pulling movement oftherear gripper' `lengthwise of the shoe, wheresuch movement occurs, `in accordance with ythe rinitial position ofthe gripper lengthwise of the shoe. Since the machine will custom arilybeusedto pull over right and left shoes successively. it `v`fu rth er includes automatic "meansffor reversing,in` each cycle, the conditions `affecting the opposite -sidc grippers in respect Ato 'their ,initi al i relative positions and in. respect tofthe relative :move-` ments that they'refceifve,- with further means whereby the imachine may be set. it'A desired. togpull over a yplurality of right shoes or of left shoes in succession.

To `render the machine more effective Ato accomplish the objects hereinabove set-forth. as well asfor other-purposes, it isI considered preferablejthat the upper be pulled'l by 'different grippers `at diiferent times,` `the maico Cil

chine herein shown having means for operatw ing the front side grippers, with their updrawing and foredrawing movement, before the rear side grippers are closed on the upper. More particularly, the construction shown comprises mechanism for delaying the action of the rear side grippers until after the machine has come to a stop at the end of the first stage of the cycle, thus affording opportunity for manipulation of theV front side gripper-s to straighten the tip before the rear grippers are closed. As one embodiment of this feature, the machine is provided with toggles which vprevent movement of the rear side grippers in response to the tensioningl of their updraw springs vin the first stage of the cycle, and manually operated means for thereafter breaking the toggles to permit the springs to act.

To render the machine effective in securing the tensioned upper to the best advantage, the invention further provides novel means for varying relatively thc positions of diiferent upper-fastening tacks or the like, the construction shown comprising mechanism whereby the devices for driving the rearinost side tacks, as well as for wiping` the upper over the insole in the corresponding locations, receive positioning movements lengthwise of the last together with the corresponding rear side grippers.

The above and other features of the in` vention, including also novel mechanism for controlling one or more grippers singly, novel foredrawing and tip straightening devices, and various details of construction and combinations of parts will now be more particularly described by reference to the accompanying drawings and pointed out in the claims.

In view of the full disclosure in Vprior patents, including those hereinabove mentioned, of the general organization of machines of the type illustrated, the present description will be confined to such portions of the inachine as it necessary to refer to 'for ar understanding of this invention.

The machine is provided, as usual heretofore, with meansfor gripping and pulling.r the upper at the end of the toe and at the opposite sides of the forepai't, the means for pulling the upper at the end of the tee comprising a toe gripper 20 which operated by an updraw-lever 22 from a cam slide 2t through an updraw-sprino 2G, the siide '2t being operated, as usual, by a cam on a cani shaft 28 which receives movement intern u; tently in the cycle of the machine. For purposes of this invention there are provided. for pulling the upper at each side of tie shoe, a front side gripper 30 and a rear side gripper 32 (Fig. 2) which are separate from each other and are operated respectively by separate updraw levers 34 and 3G. There are thus two i'ront side gripper leversy Ill; and two rear side, gripper levers- 9,6. as shown in Figs. 3 and 4, all these levers being oper ated from the cam shaft 28 by means of a single cam 38 acting on a cam slide stt). This cani slide has projecting upwardly from it two guides i-2 upon which is .slidingly mounted a yoke 44. Confined between adjustable plugs itl in the upper end of the yoke 44 and the rear ends of the several side gripper levers are four springs a8 aitording yielding connections between the yoke and the levers. The position of the yoke ti tively to the slide 40, and therefore the main initial tension ot the several springs` l, is determined b v wedge members 50, such as commonly used heretofore for a similar purpose. these members being` inserted between brackets 52 on the guides 42 and projections 54 on the yoke 44. lt will be understood that these wedge members are adjustable to vary simultaneously the tensions of the several springs 48, and it will be seen, mereloo neva-ssa ov er,'that the `tension of each-of thespri-ngs may bevaried independently of the others by adjusting its plug 46, so that the forces applied to the upper by differentside grip* pers may be `independently varied..

@While the `front and rear side grippers are thus operatedby a single cam `slide 40, the machine is providedwith means dior delay ing the action of the rear side grippers until the .front side grippers have been operated to pull the upper. For this purpose there islpivoted at 5G to each rear side gripper lever`36 (Fig. 2) one arm 58 of a toggle, the other arm of which is fast on a rock shaft 62 mounted in the frame oit the machine. Movement of the toggle arms 58 and 60 to straighten the toggle is limited by an adjustable stop 64 which is carried by the armtiO andiis arrangedto engage a portion of the frame. The two toggle arms of each toggle arejpivoted together at 66, and at the same point on.` one of the toggles there is connected to the arms a link 68 which is connected at itsrear end to a vertical arm of a bell crank lever 70 which is fasten a spindle 72, this spindle being turned in the direction to straighten bothitoggles 58,60 by means oi a spring74 (Fig. 3) when the yoke 44 is in its uppermost position. During the lirststage ofthe cycle ot operations of the ma-A chine the toggles are thus in straightened condition, so thatthe rear side gripper levers 36 are prevented from operating, notwithstanding the fact thatjt-heir springs 48 are tensioned by the downward movement ot the yoke 44 whereby upper pulling movement is `imparted to the front side grippers 30. The

.ingof thetoggles 58,60. In the machine .herein shown this isaccomplishedby a short ,depression oi the starting treadle 76 which controls the power operation of the machine, the treadle thus being'depressed while the machine is at rest after the tirst stage of the cycle, and its niovementat this time being so `limited as to prevent the actuation of the starting mechanism. For the purposes in view there is provided a rockinglever 78 pivoted at 8() on the frame otthermachine and projecting at one'end over a horizontal arm ot the bellA crank lever 70. kThe other end of the lever 78 carriesa block 82 which is arrangedtobe engaged on itslower face by the upper end of an arm 84 mounted on a l-*vertically movable l-bar 86, thisfbar being fast on theupper `end of a rod 88whichis connected at itslowerendtothe tread-lei in such manner astofpermit the rod to swing laterally. Normally `the parts are positioned as shownin Fig. 3 Withthe arm 84 rocked from underneath the block 82 bythe action on the bar 86 ott a spring 90which ris mounted on a pin 92 that passes through a slot in the bar and is tast on a bracket`94. on the `frame. Forswinging the rod 88 andzthe bar 86ste the right (Fig. 3), so asgto carry the arm 84 into position under the block 82, there isprovidedon the cam member 38, which operates'the slide 40, a peripheral cam 96 which acts through aninterposed member 98 upon a lug 100 *fast on `the rod 88. It willbe understoodthat thisaction'of ythe cam 96 takes placerinthefirst `stage of the cycle, 4so that the parts are positioned to causeithe breakingof the togglesi-58f60 by the action of the arm 84on tl1e"lever 78 `when the treadle 7 6 is again depressed; In order to prevent the trealdle 76 from being moved at this time far enough to start again `the power operation ot' the machine, movement of `the rocking lever i7 8, and `consequently moil'ement of the trcadle, is limited by an adjustable stop 102 .whichis arranged tobe engaged by the block V82 on the lever 7 8.

In order to render the starting treadle 7G again effective to start the machine after the rear side grippers `have Vbeen released and have pulledithe upper, the member 98 above referred to as interposed `between the cam 96 and thelug T100 is provided with a laterally projecting nose portion 104 which is arranged to be `moved downwardly from between the cam and `the lug to render the spring 90 effective to swing the arm 84 from underneath'the blocl82. For this purpose the member 98 is pivotally connected at its upper end to theherr/,entail` arm ot the bell `crank lever 70. lVhen', therefore,ithe toggles 58, 60 are broken, the member 98 is moved doivnwardly by the bell crank `lever 70`to release the rod and the parts thereon to the action oi' the spring 90. The member 98 `at its lower end is provided with a pin 106fwhich extends into au slot formed in a lug 108011 the rod 88 to guide the member 98 in its upward. and downward nio'vements. It will further be noted that the arm 84 is pivotally mounted on the slide 86's() that it may yield laterally against the resistance of a spring lll) to avoid piinssible iflanger o'l' breakage. 1 Machines olf the type `shown in the prior patents herein before mentioned are now usually provided with a `fluid cheek or dashpot t'or reta rding the upper pulling movement et the two opposite side gripper levers, as described inV Letters Patent No. 1,169,414,

i granted on January 25, 11916,upon an-ap y plcation of R. F. MeFeely, and in thel laterally 0f the Shoe.

chine herein shown the four side gripper levers are controlled by such retarding mechanism through connections arranged to permit different levers to move at different times. This is especially desirable in the case of the rear side grippers, which are suddenly released to the action of their previously tcnsioned updraw springs. By reference to Fig. 1, it will be seen that the plunger rod Each of the pins 128 is connected by a linky 130 and a spindle 132 to both the side gripper levers 34 and 36 at the corresponding side of the machine, there being provided hall and socket connections between the link 130 and the pin 128 and the spindle 132, and also between the spindle and the gripper levers. By these connections the different gripper levers are permitted to move relatively toy one another, and the retarding mechanism is rendered effective on the dilferent side grippers irrespective or the time of action and the extent of movement of the different grippers.

The machine is further provided with lneans of the salne general character as that shown in the prior patents mentioned for effecting and controlling movements ot the ide grippers toward and from each other There is thus a wedge member 134 (Fig. 10)` which is moved longitudinally of the machine to force the opposite side grippers apart or to permit them to move toward each other, this wedge member in the machine herein shown being arranged to act upon gripper controlling slides or cages 136 eac-h of which carries a roll 13S in engagement with the wedge member. Each of the `front and rear side grippers 30 and 32 comprises a gripper casing 140 and an updraw bar 142, and each of the gripper casings 140 has thereon a projection 144 to stop its downward movement, substantially as in prior machines ot the same general type. In the construction herein shown the pro' :ch tions 144- oll the gripper casillas are ari-ai @ed to engage a front bar 146 of, the cage- 136, the front and rear side grippers being conined between this bar and an intermediate bar 148 so that they will be moved laterally of the shoe by movement of the cage 136, there being provision for movement ot each of the side grippers lengthwsie of the shoe relatively to the cage, Each cage 136 is pressed inwardly by means of a compression spring 150, so that this spring imparts overdraw movement to the grippers when permitted by the wedge member 134.

Connected to the front side grippers, in the machine herein shown, is mechanism for imparting to these grippers in their updraw movements foredrawing movements toward the toe end of the shoe, this mechanism being constructed also -for use in moving these grippers relatively to each otherlengthwise of the shoe for straightening the tip. By reference to Fig. 2 it will be seenthat the casing 140 ot the front side gripper 30 is connected hy a ball-andsocket Joint to a long link 152 which extends forwardly and at its iront end is connected to a pivot pin 154 adjustably secured to a slotted link 156 which is mounted indirectly, as hereinafter described, on the frame of the lnachine. When the gripper receives its updraw movement, the pivot pin 154 is held by the link 156 in a fixed position, so that the link 152 acts in response to the updraw movement of the gripper to impart to the latter also a foreclrawing movement, the extent of which is determined by the position of the pivot pin on the link 156. By adjustment of the pin 154 along the slot in the link 156 the extent of the foredraw may be varied from a maximum practically to zero. It will be understood that the connection between ,the link 152 and the pin 154 is such as to permit the link to swing to some extent from side to side as well as vertically, thus allowing for the in and out movements of the gripper laterally of the shoe. There are separate slotted links 156 and connecting links 152 for the opposite 'front side grippers, as indicatedin Fig, 7, so that the extent of the ioredrawing movement of either Vof these grippers may be variedV independently vof that ofthe other gripper.

Each link 156 has extending rearwardly therefrom at one end an arln 158 which is hung by means of substantially parallel links 160 and 162 on the frame of the machine, so that the link 156 and its arm 158 may be moved bodily lengthwise of the shoe. Such movement of these parts is utilized for tipstraightening purposes, under control of a rock shaft 164 which has fast thereon a hand lever 166. Fast on the rock shaft 164 is a member 16S provided with a pair of crank pills 170 and 172 mounted 180 apart and connected respectively by links 174 and 176 to the dierent respective link members It will thus be evident that when the. hand lever 166 is moved in one direction or the other, the front side grippers will he moved simultaneously in opposite directions respectively lengthwise of the shoe. In order to return the parts of the tipestraightening lnechanism to normal position at the end of the cycle of operations, each of the links 160 has an upward extension on which is lnounted an abutment member 17 8, and the members 178 are arranged to be engaged, as illustrated in Fig. 10, by members 1870 corresponding to the members 882 of Patent No.` 663,777), which are a part ofthe means profk vided tor imparting inward and `outward movements to the overwiping and tasking mechanisms and in the return ofthe parts" of the machineV to startingposition have a downward and forward movenientianchas tol move one or the other olf' the nlemhors 178 `'tomvardly. 1

It is preferred that, in operating on right and left shoes, the oppositeI rear side grip'-` pers 82 be differently positioned lengthwise of the shoe, in such manner, for example, thatthe gripper 4which pulls theuppcrat the. ontersideof` a shoe shall be.positionedtiar--`V ther` from the toe end 4ot the shoe than the gripper which pulls at the `inner side fof the shoe. Thei'machinelis accordingly provided with la pair of slides182 connected respectivelyA tothe di-:lerent rear side grippers by mechanism hereinafter described, these slides heingmounted for movements llengthwise of the shoe and connectedby rods 184 to cranlr` pns186which are monnted on-cranlr discs 188 fast on a transverse shat 190 (Fig. 7); For operating the shaft 190 there` is utilized a slide 192 (Fig. 2) which is provided in maehinesof this general type for controlling the shoe-supporting heel rest" 193, this slide being moved toward the left (Fig. 2) in the i first stage oflthe cycle,` and movedtoward the` right near theend of the cycle. Mounted on the slide'192 is a stud 1941 projecting through a slot in a casinglilf which' encloses the slide, this stud having mounted thereon a block198 which is slidably positioned between jaws 200 formed upon one end of a lever202 whieh'is pivoted at 204 on the .frame The other' end of the `lever 202 is provided with` gear teeth `206` l meshing with `a pinion-208 Fig. 8) which is mounted `toitnrn` about ithe sha'lit 190. The pinion 208 carriesaplate 21() which has mounted thereon a `pawl` 212 adapted to enter oney or` the other 'oftwo notches 214; formed at opposite sides ofoneA oit the crank discs188.` It will th'ns bel seen; that'in the first stage of the cycle of the machine the pawl 212 is carried `from one to the other oi' the notches 214, andthat near the endlof the cycle, after the; operationson as shoe `have been completed, the shaft 190 is turned by the pawl through 1808. 'Ihecranlr` pins 186 are positioned 180O apart'andarefso arranged that when `the shaftlQO istnrned, as` ahove described, one-of the slides 182 is moved forwardly and `the other slide; is moved rearwardly, thus reversing the positions lengthwise of the shoe of the-opposite rear side grippers prior to theoperation `of the machine on the nest shoe, it being assum-` ed that the two shoes of a pair will be` pulled successively. In orderto provide orpulling over a plurality of right or ot left shoes" successively, when it is desired tooperate the machine in this manner, there is fixed to one ses of the crank discs 188 a hand piece 216 so that theshaft 190 can he turned independently of the action ot' thepand 212. In order to indicate to the operator when the shaft 190 has thus been turned theprolier distance, a spring-pressed catch 218 is arranged to enter one or the other of two notches 22() located 180o apart in that cranl disc 188 whichison tliefopposite side ot the machine from the pawl `212. is herein` shown, each of the crank discs 188 is provided with a slot` 222 in, which theel-ank pin 186 is adjustable to vary the throw ofthecranli pin from zero toa n'uiximum.` In this manner the positions; of the rear side grippers length# wiseioftheishoe maybe varied, or the grippers" may `he positionedinvariably at the sameidista'nce. from the toe end of the shoe in operating upon successive shoes. There is yalso provision for varying the initialA position of either rear sideigripper for any given throw of the crank pin, each rod 184 having a slot 223 therein lto permit it to be adjusted lengthwise relatively tothe crank pin.

`The connections between each of theslides 182 and the rear side gripper adjacent there to are shown in detail in Figsl and `7. Each slide'182 is provided with a head 224 extending laterally lin both directions, and mounted in this head is a spindle 226 onwhich is a block 228 provided with a-guideway 230. ll'lounted in the guideway 230 is a slide 232 provided with a recess in which is pivotally mounted a dise 234 extending from which is a link; 236 havingthereon a `collar 238 locatedin a recess in the gripper casing 140. As the slide 182 is moved lengthwise of theshoe the gripperA is thus carried with it, si'ncethe parts are so formed that the slide 2,32 is eontined within the guideway 230.

`The spindle 226` is rotatably mounted in the` head 224 sothat the block 228 may loe` positionedA with its guideway 280 and slide 232 in different angular relationsto lthewdirection ofthe updraw movement of the rear sidergripper, andin `this manner the gripper may be made to have a component ofmovement lengthwise of thev shoe, either forwardly or rearwardly, in the upper-pulling operation.` Themachine is `tur-ther provided with means for controlling the guide blocks 228 and i'orpositioning them in response to the i gripper-positioning movements of the slides 182so as to determine thel direction andextent of the movements of the rear side grippersj lengthwise of the shoe in accordancewwiththeir positions lengthwise of` the shoerv For this inirposefeach block 228 is providedwithgear` teeth 210 in `engagement-withteeth 242 formed on a` sleeve2114 which is fast on a-roclrshatt246monntcd in the slide 182, and onone end of thevroclr shaft 24,8 isaicrank arm 248 connected to a member2M-arranged to slide in a guideway formed in a guide block 252 which is adi justably pivoted on a pin 254 on the trame of the machine. The guide block 252 may be set manually in different positions so that its guideway is in any desired angular relation to the direction ot' movement ot the slide 182 or is parallel thereto. In this manner the rock sha't't 246 may he made to turn in either direction, to any desired extent, in response to the gripper-positioning movement ot' the slide 182, so as to position the guide block 228 to impart to the rear side gripper either oredrawing or reardrawing movement of any desired extent, or by the setting ot' the block 252 any such movement of the gripper lengthwise otthe shoe in the upper-pulling operation may beeliminated. It may he preferred, for example, to adjust the parts so that the rear side gripper which operates at the outer side of the shoe shall have a reardrawing movement as it pulls the upper, While the gripper which operates at the inner side ot the shoe has a. oredrawing movement. The guideiblock 252, when set in angular' relation to the direction of movement ot the slide 182, causes a reversal of the inclination of the guide 228 relatively to the direction of the updraw movement ot' the gripper in response to movement ot the slide 182 from one extreme to the other, and in this manner the direction of the movement of each-rear gripper lengthwise of the shoe is changed as its position is shifted for rights and lefts. As the grippers are moved laterally of the shoe, the guide blocks 228 are carried with them, each lspindle 226 being slidably mounted for this purpose and the teeth 242 onthe sleeve 244 being long enough to permit the teeth 240 to continue to engage them in any position of the gripper. It will further be understood that the connections described between the slide 232 and the gripper casing are such as to permit the required relative movements between the gripper and the guide block 228.

The machine is also provided with means for wiping the upper inwardly over the insole and for driving upper-fastening tacks at the toe end and at the opposite sides of the shoe, this mechanism being similar in its general organization to the upper-fastening mechanism'ot prior machines as shown, for example, in Patent No. 1,029,387, there being provision for driving three tacks at each side, of which two are driven adjacent to the front side gripper and the third adjacent to the rear side gripper. j Each of the side wiping and tacking mechanisms comprises, as usual heretofore, a side driver bar arm 256 mounted for swinging movements laterally of the shoe, and a driver bar 258 mounted in the arm 256 for operating the tack drivers. The means Jfor operating and controlling the driver har arms 256 and the driver bars 258 is of substantially the same construction as in prior' machines. In view of the provision in the present machine of means for effecting movements of the rear side grippers lengthwise of the shoe, the machine is provided with means for similarly varying the positions ot the overwiping and tacking devices which drive the tacks adjacent to vthese grippers. It will be seen that there is mounted for sliding movement on the head 22st a carrier 260 which is provided at its inner end with overwipingand tacking devices, indicated generally' at 262, which are substantially the sameconstruction as the devices provided for overwi ing and tacking the ripper at the toe end o the shoe in the machine shown in Patent No. 1,029,387. Since these overwiping and tackin devices are mounted on the head 224, it wi l be evident that they are moved lengthwise of the shoe with the corresponding rear side gripper when the grijfiper receives such movenient from the operation i the slide 182, the driver bar arm 256 being restrained from movement therewith. Included in the tacking mechanism 262 which is'mounted on the carrier 260 is a slide 264 for operating the tack driver.v Y

Mounted for swinging movement coaxially with the arm 256 at the front side thereof is Vanother arm 266 which carries at its lower end overwiping and tacking devices indicated generally at 268, which are similar to the devices 262 but so modified as vto drive two tacks adjacent to the front side gripper. The driver bar arm 256 is provided at its lower end with an outwardly projecting boss 27 0 upon which is pivotally mounted a rocking lever 272, adapted to serve as an equalizing lever, the opposite ends ot-whichk are arranged to contact respectively with an abutment face 274 on the carrier 260 and with an abutment 276 on the arm 266. Two springs 278 and 280 connect the lever 272 to the carrier 260 and the arm 266, so that the overwiping and'tacking devices. 262 and 268 accompany the driver bar arm 256 in its inward and outward movements but are permitted to move relatively to cach other to accomodate their positions to shoes of ditierent shapes. The lever 272 has on its outer side two faces which are arranged to Contact with a bracket 282 on lthe frame of the machine when the driver bar arm is moved to its outermost position, so that the wiping and tacking devices are always centralizedwhen they are returned to inoperative position ready to receive tacks preparatory to a new cycle of operations.

The driver har 258 has near its lower end a pivot 284 upon which are mounted two swinging links 286 provided with clawshaped lower ends to enter a recess in the lower end of the driver bar to prevent movement of the links away fromy the driver bar.

accesos One of these links has on `its lower end a lug 288 which projects into a slot termed inY a driver slide 29Omo`unted` upon the swinging arm 266, this slide carrying at its lower end tack drivers for driving the two tacks adj acent to the front side gripper. The other link i286 carries Ia lug 292 which provides a similar connection between the link and the driver slide 264 for driving the rear tack,`

this lug, however, being elongated to allow for the movement lengthwise of the shoe ot the rear wiping and tacking mechanism 262. It will be understood that this construction `provides a continuous connection between the driver bar S and the driver slides 264 and 290 whatever may be the relative positions of the different overwiping and tacking devices. j Y

l In the operation of the machine, briefly summarized, the operatorp'resents to the machine a right or a left shoe, depending upon the setting of the side pulling and tacking devices as determined at the end of the preceding cycle, or in ease the machine is not set to operate upon that'shoe of a pair which he has in hand, the operator may so adjust 'it by turning the shaft 190 by means of the memberlt. `In the first'stage of the cycle the upper is gripped and pulled by the toe gripper 20 and by the front side grippers 30, the latter receiving a toredrawing movement ift-he links 152 are adjusted, as they preterably will be, to ei'ect such movement. In this stage of the Cycle the rear side grippers 30 are prevented from closing by reason of Then the shoeiis in proper condition for the rear side grippers 32 to act, the operator againdepresses the starting treadle 476, which is prevented by the stop 102 from moving tar enough at this time to start the machine, and which, therefore, acts only to break the toggles 58, and thereby to release the rear side gripper levers to the action of their tensioned updraw springs. The rear side grippers are thuselosed and operated to pull the upper, and `if their controlling devices are adjusted to produce the results hereinbefore described as preferable, that rear gripper which operates at the outer side-of the shoe receives a reardrawing movement while the rear gripper at the inner side ot the shoe receives a foredrawing movement durmg' the4 updraw. The operator is then enabled again to inspect' the, shoeand to eti'eet any further manipulation ofthe front side" grippers that may desirable. j

Vhen the machine is again started by depression ot the starting treadle, the: overdrawing and overwiping operations andthe uj'iper-tastening operations talee pl- -e. both at the end oi' the toe and at the sides ot the forepart, in the well-known manner, the spacing appear to` be necessary 01 ot the side tacks being so determined that the rea-rmost tact: at the outer side ot the shoe is positioned tarther rearwardly than the correspoinhng tack at the inner side. 1n

the return oi the parts of the machine to positions ot rest the side pulling andtacking devicesl are set automatically to operate" in the next cycle upon the other' shoe ofthe pair, this setting ot' the partsiueludingthe positioningl of that rear side gripper which is to operate at the outer side ot the next shoe `farther rearwardly than the corresponding" `gripper at the other side. f
